57	Abstract	AB	Die Erfindung bezieht sich auf ein Verfahren und eine Schaltungsanordnung (10) zur Helligkeitsregelung von zumindest einer LED (12), wobei in die zumindest eine LED (12) ein Pulsstrom I↓PULS↓ mit Stromimpulsen bestimmter Pulsamplitude und Pulsdauer eingeprägt wird und wobei zur Helligkeitsregelung die Frequenz des Pulsstromes I↓PULS↓ variiert wird. Der Erfindung liegt die Aufgabe zu Grunde, sowohl beliebig viele LEDs gleichmäßig und ruckfrei in ihrer Helligkeit zu regeln, als auch eine möglichst geringe "Grundhelligkeit" zu erzeugen, so dass ein für das menschliche Auge nicht sichtbarer Übergang von 0% auf die unterste Helligkeitsstufe verwirklicht wird. Zur Lösung wird vorgeschlagen, dass durch Variation der Pulsstromamplitude des Pulsstromes I↓PULS↓ ein Helligkeitsbereich vorgegeben wird und dass innerhalb des Helligkeitsbereichs durch Variation der Pulsstromdauer und/oder der Pulsstromfrequenz eine gewünschte Helligkeit eingestellt wird.
